COX communications

I happen to work in the internet business. I work for AT&T. I have for over 20 years.
I have installed and repaired all sorts of internet issues. With Cox, to get Max advertised speed, you need a home run, that is a dedicated coax run from the MPOE, where it comes into your home. NO spltters on the line. Cox repairman needs to check speed at MPOE and at modem location. And compare. If slow speed is seen at MPOE than Cox needs to fix. MPOE is the legal term for Minimum Point Of Entry. where the wiring goes from coxes responsibility and where yours starts. MT
